I have a Makita HR2475 rotary hammer drill. It will not take a drill bit – I push one in and turn but it does not engage. Help!
Bad chuck spring possibly? Take the chuck apart and have a look for the culprit. Here is parts diagram.
Here is where to get your parts:

it can be cylinder number part 25 worn out. It have pins inside it (they hold drill bid to not spin in inside of the cylinder) if you not see that pins you need new cylinder. And you must check part number 5 if it`s not worn out and of course your drill bit
Are you using SDS bits. Standard bits will not work in a SD Rotary Hammer. Please don’t think that I don’t think you don’t know what your doing . I have seen many guy buy a SD Rotary Hammer not realizing they need SDS bits. It is an honest mistake.
